Embodiment

[0078] (1) In this embodiment, the surveillance video in a certain scene captured by the standard camera equipment is used as the input natural video, and the encoding format is the standard AVI format.

[0079] Load the grayscale image corresponding to the video frame sequence. The format of the grayscale image is the JPG image encoding format, and the size of the image is 400×293 pixels. The foreground extraction and binarization process is performed, and the background frame clipping is improved for background extraction. Algorithm, the binarization uses the adaptive threshold filtering algorithm to obtain the binary silhouette frame sequence of the monitored person's movement, and construct the motion history with the binary silhouette frame sequence of the specified frame length for a specified action sequence to be learned image. Such as figure 1 , a frame in the binary silhouette frame sequence obtained in the embodiment.

[0080] For a binary silhouette frame sequenc...

Abstract

The invention discloses a real-time intelligent monitoring method based on natural video. The method uses the knowledge of computer image processing and artificial intelligence and realizes unmanned intelligent monitoring and alarm to the action of pedestrian in public places and important sensitive places. Firstly, video frame serial sections which need to be studied are extracted, movable historical images are obtained, which reflect the movement process of the people; on this base, the user-defined method for extracting the eigenvector is used, vector representation of the specific movement series is obtained, and the vector sample is stored in the sample database; as for the video frame serial which need to be monitored, the eigenvector and sample data are mapped in the low dimensional space, the corresponding classification by the optimized method is obtained and alarm is carried out. Owing to the sample study mechanism and the classification mechanism of the designed actions in the text, the method of the invention improves the accuracy of identification and strengthens the expansibility of identification; by designing the eigenvector representation and extraction method of movement serial of the people, the completeness and accuracy of action representation are strengthened.

Description

technical field [0001] The invention relates to an intelligent monitoring method, in particular to a method for processing natural video based on computer image processing and artificial intelligence knowledge to obtain real-time intelligent monitoring of a specific scene, which belongs to the comprehensive field of computer image processing and artificial intelligence. Background technique [0002] With the rapid growth of urban population and the increasingly complex urban environment, urban social security incidents such as mass incidents, riots, and terrorist attacks have seriously affected urban public security. Building a safe city has become an important topic in today's international community. When it comes to the construction of "safe cities", people will naturally think of the terrorist incidents that have occurred around the world in recent years. After the "911" terrorist attack in the United States and the London subway bombing in the United Kingdom, governmen...
